Device for adjusting a harness line for a sail-board

Abstract

The invention relates to a device for adjusting the attachment points of a harness line (2) on a boom (1) for a sail-board or the like. It is in particular remarkable in that it includes a carriage (3) that is mounted sliding inside or outside the boom (1) or in an attached part. The harness line (2) passes through the passage orifices of the carriage (6a-6b) in order to form a loop (4), which allows the user to hang by his harness. The carriage (3) can be locked by an appropriate system. This device makes it possible to correct the position of the loop (4) easily during operation of the sail-board in the water by unlocking the carriage, sliding it and locking it in a new position. The length of the loop (4) can be adjusted by shortening or lengthening the harness line (2) with a clam cleat.

What is claimed is: 
     
       1. A device configured for adjusting a position and length of a harness line on a boom of a sail-board with a single hand, wherein the device comprises:
 a carriage comprising a first orifice and a second orifice, wherein the carriage is configured to slide relative to a portion of the boom, wherein the carriage comprises a locking system configured to control sliding movement of the carriage; 
 a harness line passing through the carriage and creating a loop between the first orifice and the second orifice of the carriage; and 
 a first stop and a second stop fastened on the boom, wherein the first stop is configured to retain a first end of the harness line and the second stop is configured to retain a second end of the harness line, and wherein the second stop comprises a clam cleat configured to allow shortening or lengthening of the harness line between the first stop and the second stop. 
 
     
     
       2. The device of  claim 1 , wherein at least a portion of the boom over which the carriage is configured to slide is fitted with a cylindrical sleeve mounted over the boom, and wherein the cylindrical sleeve comprises a channel to house at least a portion of the harness line between the first stop and the second stop. 
     
     
       3. The device of  claim 1 , wherein at least a portion of the boom comprises a channel to house at least a portion of the harness line between the first stop and the second stop. 
     
     
       4. The device of  claim 1 , wherein the carriage is configurable to form different lengths via arrangement of a plurality of modules comprising:
 a first ring comprising the first orifice; 
 a second ring comprising the second orifice; 
 an adjustable spacer configurable to adjust separation between the first orifice and the second orifice; and 
 the locking system on the boom. 
 
     
     
       5. The device of  claim 4 , wherein one or more of the first ring, the second ring, the adjustable spacer, or the locking system are combined to form a single component. 
     
     
       6. The device of  claim 1 , wherein the carriage is open-worked and configured to allow cleaning of the carriage with water. 
     
     
       7. The device of  claim 1 , wherein the carriage comprises a plurality of rolling members configured to facilitate sliding movement of the carriage along the boom. 
     
     
       8. The device according to  claim 1 , wherein the first orifice comprises a first pulley, wherein the second orifice comprises a second pulley, and wherein the first pulley and the second pulley are configured to facilitate sliding of the harness line. 
     
     
       9. The device of  claim 1 , further comprising:
 an adjustment system configured to facilitate positioning of the carriage along the boom. 
 
     
     
       10. The device of  claim 9 , wherein the adjustment system comprises a thumb wheel configured to enable rolling of the carriage along the boom. 
     
     
       11. The device of  claim 1 , wherein at least a portion of the boom comprises a protuberance comprising:
 an inner groove configured to guide sliding of the carriage along the boom; and 
 a notch passing through at least a portion of the protuberance forming an opening configured to allow the harness line loop and partially a locking clip to pass outside of the protuberance. 
 
     
     
       12. The device of  claim 1 , wherein at least a portion of the device is enclosed within an inner tube having a first end and a second end, wherein the inner tube is at least partially enclosed within the boom, and wherein the first end of the inner tube and the second end of the inner tube are configured to prevent water from entering at least a portion of the boom.
